2 cups all-purpose flour
1 (16-ounce) package shredded Cheddar cheese
1 (1-ounce) envelope dry onion soup mix
In a medium bowl, knead together butter, all-purpose flour, Cheddar cheese and dry onion soup mix. Divide into two equal portions. Form each portion into a log shape. Wrap with wax paper. Chill at least 1 hour in the refrigerator, until firm. Preheat oven to 400°F. Cut the log shapes into slices approximately 1/8-inch thick. Arrange slices in a single layer on a large baking sheet. Bake 12 to 14 minutes in the preheated oven, or until lightly browned.
